Headers should be in the form ==Header==, not the form == Header ==. This only applies to articles, image pages use == Summary == automatically and talkpages are free form and no changes should ever be made to header style.

Do not go adding last names to links unless you have a valid reason to do so (full character name hasn't been used earlier in the article). Full names should not be abused to bypass redirects.

Do not change page numbers in ref tags to have a leading zero. Going around the wiki and changing 3 to 03 despite most pages sticking to 3 doesn't improve the wiki at all and just adds pointless edits, just stick with 3.
